To perform a hard reset (force restart) on an iPhone, the exact button sequence depends on your iPhone model:

For iPhone 8 and later (including iPhone X, 11, 12, 13, 14, 15, and

newer):

1. Press and quickly release the Volume Up button.
2. Press and quickly release the Volume Down button.
3. Press and hold the Side (Power) button until the Apple logo appears, then release it

For iPhone 7 and iPhone 7 Plus:

1. Press and hold the Volume Down button and the Sleep/Wake (Power) button simultaneously.
2. Keep holding both buttons until the Apple logo appears, then release

For iPhone 6s and earlier (including iPhone SE 1st generation):

1. Press and hold the Home button and the Sleep/Wake (Power) button at the same time.
2. Keep holding both buttons until the Apple logo appears, then release

Notes:

• A hard reset forces the iPhone to shut down and restart, which can resolve software glitches or unresponsive behavior without deleting your data

• This is different from a factory reset, which erases all content and settings from the device

• If your iPhone is frozen or unresponsive, a hard reset is often the first troubleshooting step to try

This method is effective for troubleshooting and restoring normal operation when the device is stuck, frozen, or not responding.
